Coca-Cola: Rainbow Nation Rainbows

A rainbow you can actually chase across Johannesburg

Twenty years ago, South Africa elected Nelson Mandela in the country’s first-ever democratic election. This led Archbishop Desmond Tutu to coin the phrase “The Rainbow Nation,” referring to the country’s diverse people.

Now to celebrate this 20th anniversary of democracy, Coca-Cola decided to literally create rainbows. Using sunlight, water, some fancy science and a little bit of magic, they made rainbows pop up all over Johannesburg. Some rainbows even reached the ground, for those who sought to discover where they ended.

The trick: make the symbol physical

This is not a graphic. It is a phenomenon placed into normal streets. And the moment the rainbow reaches the ground, the campaign stops being something you watch. It becomes something you can follow. This works best when the symbol becomes a physical invitation, not a slogan.

The real question is whether people can choose their way into the meaning, instead of being told what it means.

Why discovery beats declaration

You are not told what to feel. You either stumble into it and smile. Or you choose to go looking for the end. That voluntary participation is what makes it feel like magic, not messaging.

Extractable takeaway: If you want participation, turn the message into a small quest people can opt into, not a statement they are asked to agree with.

In city-scale brand activations, the strongest participation comes from turning a familiar symbol into a discoverable experience people can physically encounter.

What it was really celebrating

Twenty years of democracy, expressed through a shared symbol, brought to life in the city.

Ideas worth borrowing

  • Turn an abstract story into something people can encounter in the real world.
  • Add a simple “seek and find” layer so curiosity becomes the call-to-action.
  • Keep the explanation light. Let the experience carry the meaning.

A few fast answers before you act

What did Coca-Cola do for “Rainbow Nation”?

They made rainbows appear across Johannesburg to celebrate twenty years of South African democracy, including rainbows that reached the ground.

Why is the phrase “Rainbow Nation” used?

Archbishop Desmond Tutu coined “The Rainbow Nation” to describe South Africa’s diverse people following the country’s democratic transition.

What was the viewer experience?

People encountered rainbows in public space, and some could be followed to the ground to discover where they ended.

What is the core creative mechanic?

Transforming a cultural symbol into a real-world phenomenon people can discover in the city.

How do you recreate this idea without a rainbow?

Pick a symbol your audience already recognizes, make it physically encounterable, and add a simple “seek and find” hook so people choose to participate.

Coca-Cola: Give a Coke, Be Santa

A vending machine that asked you to choose who you are

The strongest holiday ideas turn seasonal sentiment into a simple action people can take in public. Coca-Cola’s holiday vending machine is a clean example of that move.

Coca-Cola wanted to bring out the Santa in everyone. So for the 2013 holiday season, they created a special vending machine that prompted users to either get a free Coke or give a free Coke.

The two-button mechanic that made sharing the story

If the user chose a free Coke, the machine quickly dispensed the drink for the user to enjoy.

However, if the user decided to share, then the machine did something a little more special. Watch the video below to find out.

In high-traffic FMCG retail settings, a binary choice lets a brand value show up as behavior in seconds.

Why “give” feels better than “get” in December

The psychology here is straightforward. A free product is nice, but it is forgettable. A choice that reflects identity is sticky.

Extractable takeaway: If you want a value like generosity to travel, put it into a visible choice where the “better self” option is easy to pick and easy to witness.

By putting “give” and “get” side by side, the machine turns a small decision into a moment of self-image and social proof, meaning other people can see the choice and validate it. During the holidays, people want to see themselves as generous, and they want to be seen that way by others.

The business intent behind bringing out the Santa

The intent is not simply distribution.

The real question is whether your brand promise can be expressed as a choice people are proud to make in public.

This is a stronger holiday move than a message-only campaign because it makes the value legible and repeatable at the point of interaction.

Coca-Cola uses the vending machine to translate a brand promise into behavior. The brand is associated with warmth and sharing because the consumer enacts it, not because the brand claims it.

How to reuse this give-or-get choice design

  • Turn values into a choice. Make the brand idea something people can do, not just hear.
  • Reward the “better” behavior. If sharing is the story, make sharing the more memorable path.
  • Keep the interaction instantly legible. Two clear options beat complex instructions in public spaces.
  • Design for a public moment. When others can witness the decision, the story travels faster.

A few fast answers before you act

What did Coca-Cola build for the 2013 holiday season?

A special vending machine that offered users a choice: take a free Coke or give a free Coke.

What was the core mechanism?

A simple two-option prompt. Choosing “get” dispensed a Coke immediately. Choosing “give” triggered a more special outcome.

Why does the “give” option matter so much?

Because it turns a freebie into an identity moment. People remember what they chose, and others can witness it.

What business goal did this support?

Making Coca-Cola’s holiday positioning feel real by linking the brand to a visible act of sharing, not just a message about sharing.

What is the main takeaway for brands?

If you want to own a value like generosity, design an interaction where people can demonstrate that value in the moment.

Pepsi Max: Unbelievable Bus Shelter

Pepsi Max for its new ‘Unbelievable’ campaign rigged an ordinary bus shelter in London, to perform tricks on unsuspecting travellers.

Using a custom see-through digital display, people waiting at the bus shelter were made to believe that they were actually seeing things like hovering alien ships, a loose tiger, a giant robot with laser beam eyes and so on.

The reactions to these ‘unbelievable’ scenarios were then captured and put in the below viral video.

Why this works. Even before you talk about “tech”

The technology is impressive, but the mechanic is simple. Here, “mechanic” means the repeatable audience interaction pattern, not the underlying tech. It takes an everyday moment. It inserts a believable layer of impossible. Then it lets people do the rest. React, laugh, point, film, share. Because the impossible is framed inside a familiar “window”, disbelief lands fast and reactions become the content. In high-footfall urban out-of-home environments, a brand moment has to work wordlessly, in seconds, for strangers who did not opt in.

Extractable takeaway: If you can turn passive waiting time into a personally witnessed story, you get emotion, proof and distribution before you spend on media.

That is the real move. It transforms passive waiting time into a story that feels personally witnessed.

The bus shelter as a “media product”

This activation treats the bus shelter like a product interface, not just a placement. It has inputs and outputs. Here, “activation” means a physical installation that creates a live brand experience in public space.

  • Input. People arrive with low expectations and spare attention.
  • System. A “window” that looks like reality, then breaks it in a controlled way.
  • Output. Instant emotion, social proof from nearby strangers, and a camera-ready moment.

In other words, it is not only out-of-home. It is an experience designed to be recorded and re-distributed.

The real question is whether your experience turns bystanders into witnesses, and witnesses into voluntary distribution.

What makes it shareable. And why the video is the second product

The live moment is the first product. The viral video is the second product. The second product extends the reach far beyond the street corner.

Tech is optional. If the premise is not instantly legible, it will not travel.

  • High signal in seconds. You understand what is happening instantly.
  • Escalation. Each new “unbelievable” scene raises the stakes and keeps attention.
  • Human faces. The reactions are the content. The brand stays present but not intrusive.
  • Social permission. If others are reacting, you react too. Then you share.

What to take from this if you build brand experiences

  • Design the moment first. The best “viral videos” start as real-world moments people want to show others.
  • Keep the premise instantly legible. If it needs explanation, it loses momentum.
  • Make capture a feature. If people will film it, stage it so the footage works.
  • Build a repeatable format. One idea, multiple scenarios, consistent payoff.
  • Let the audience star. The most believable proof is human reaction, not brand claims.

A few fast answers before you act

What is Pepsi Max “Unbelievable” in one sentence?

It is a London bus shelter activation that used a see-through digital display to create impossible scenes, then turned real public reactions into a viral video.

Is this augmented reality?

It functions like augmented reality for the audience, because it overlays illusions onto what looks like a real street view, even though the experience is delivered through a physical digital screen.

Why do people share this kind of content?

Because it triggers instant emotion and disbelief, and it is easy to explain visually. People share it to pass on the surprise.

What is the key design principle behind the activation?

Make the better story happen in the real world. Then make it easy for the story to travel as video.

What is the practical takeaway for marketers?

When you create a moment that people genuinely want to record, distribution becomes an outcome of the experience, not a separate media plan.
